Instead of the three months, now new subscribers will be able to sign up the free trial subscription for four months.

A subscription Google Play Music also comes bundled with a free subscription to YouTube Red, which gives you access to YouTube's original series and lets you watch YouTube videos ad-free.

For India users, Google is now offering one extra month of free trial subscription to Play Music.

Hypothetically speaking, someone who's never used any of the aforementioned services, as well as a few more, could probably listen to unlimited tunes online, no ads or restrictions, for around a year before paying a single dime.

Users can listen to custom radio stations on their computer or mobile device using Google Play Music service.

Most paid apps and services want potential users to experience their product with a free trial. Google Play Music typically allows triple that with a 90-day trial, but this new 120-day trial is likely the longest free trial of its kind that's ever been offered. New users in India get a free trial subscription for two months, after which users are charged with Rs 89 per month. Users can always cancel their subscription after their four months are up, which is what makes the deal worth a try.

If that is not great enough, then you should look into Google Play Music.
